I just received a startling email from a user of my company's first iPhone app, informing me that they'd learned of our new app on AppMiner and wanted to know why it was only available in the U.S. App Store. The problem? The app hasn't been released yet!<p>After a few minutes of panic, checking the actual App Store and confirming the app hasn't accidentally been released early, I realised that websites scraping the App Store listings can apparently pull information on unreleased apps. A quick search shows up three other app listings sites which have info on this unreleased app.<p>A lot of effort's gone into planning the release of this app, and it's frustrating to have information leak early. Not a disaster in this case, but not great - for example, the price point listed is wrong.<p>So be warned: make sure your app metadata is ready for public consumption before your app exits the review process - whatever you've set its release date to!
